Abstract
A keyboard device includes a base plate, plural keys and a membrane circuit board. The keys are connected with the base plate. The membrane circuit board is arranged between the keys and the base plate. The base plate includes at least one elastic vibration absorber corresponding to a keycap or a stabilizer bar of the corresponding key. While the keycap is moved downwardly relative to the base plate, the sound resulted from the collision between the keycap or the stabilizer bar and the membrane circuit board or the base plate is reduced. Consequently, the operating comfort to the user is enhanced.
